In the present study, the relational construction between body composition and physical fitness is confirmed regarding physical fitness based on polynomial regression evaluation of body fat percentage for body mass index (BMI) in adolescence. The sample size consists of 384 Korean junior high school students aged 13 years (boys: 200; girls: 184). Height, weight, BMI, body fat mass, body fat percentage, soft lean mass were measured along with physical fitness tests (sit & reach, 20 m-shuttle run, push up and sit up). Physical fitness showed a significant difference among "slim type", "normal type" and "fatty type" classified by the fatty-slim degree judgment of BMI. Next, a polynomial regression evaluation chart of fat percentage for BMI was constructed in order to verify physical fitness by the difference of body form quality. Physical fitness was examined based on difference in the degree of qualitative accumulation of fat (excessive fat, normal fat underestimated fat) derived from the evaluation chart. As a result, the excessive fat person was significantly inferior and the underestimated obese person was significantly superior in endurance ability in the normal type. There was a difference in physical fitness based on the difference in the degree of qualitative accumulation of fat. This suggests that the fat was a negative factor for endurance ability in normal type based on the fatty-slim degree judgment of BMI.
